Carbon Dioxide Sensor Helps Detect Grain Deterioration and Insect Infestations

AgriDry LLC in mid-December added a carbon dioxide sensor option to its Bullseye grain moisture and temperature controller.

According to President Eli Troyer, “When grain begins to deteriorate or become infested with insects, it will give off a high level of carbon dioxide. Our CO2 sensor is able to detect that before it diminishes the quality of the grain.”

Troyer says the 4-inch-x-8-inch sensor is mounted on the inside of the bin rooftop and measures carbon dioxide, head space temperature, as well as head space humidity.

“With the CO2 sensor, you are able to set alert thresholds on our ADLink cloud-based software, so you receive a message when carbon dioxide reaches an irregular level inside the bin.”

Bullseye Controller

AgriDry’s Bullseye controllers are self-contained units mounted on the outside of grain bins.

Troyer says the Bullseye controller can be equipped with thermocouple cables housing 24 temperature sensors, a digital static pressure gauge mounted below the false floor, a digital moisture cable to measure grain moisture and relative humidity inside the bin, and the new CO2 sensor to monitor carbon dioxide.

“When conditions in the bin become irregular, the Bullseye controller takes action by automatically operating the necessary combination of aeration, exhaust, and heating systems to return the grain to its desired condition,” he adds.
